Scared to use my sketchbook....

[Mike Tenebrae]

Just dive in feet first, stop caring about it and treat is as it is. A sketchbook. :) Meant to be taken everywhere with you and get dog eared and coffee stained, fill up blank spots with new doodles and sketches. Stop using an eraser and just carry pencils or pens with you. I have mine with me a lot, even put them next to the bed. If in a moment of inspiration something looks cool that I want to follow up on, I'll either transfer it to a working surface or scan it.

I think its a pretty normal feeling, its why I don't really go for expensive sketchbooks.
